1.
amount of air that always resides w/i the lungs and functions to prevent lung collapse; amount after max. expiration.

2. Where does gas exchange occurs?

3. As the branch move deeper into the lungs what happens?

4. larynx receives air from

5. high levels of c02 cause what to happen to the ph?

6. The trachea is also known as

7. Alveoli

8. line the respiratory tract and secrete mucus and other liquids to both keep the lungs moist and trap inhaled pathogens

9. How does the larynx produce sound?

10. decreased blood pH <7

11.
-flap of cartilage that covers the entrance to the pharynx during swallowing, preventing liquids and food from entering the respiratory tract and trachea

12. Prolonged hyperventilation would most likely result in which of the following?

13.
nose ->nasal cavity ->paranasal sinuses ->oral cavity ->pharynx ->glottis ->larynx

14. How does the medusa oblongata control breathing?

15. maximum volume of air that can reside in the lungs

16. the pulmonary venules deliver blood to

17.
-recessive gene causes normally slippery mucous secreted in lungs/airways to become thick & sticky, clogging airways.
-this leads to difficulty breathing and susceptibility to bacterial infections.

18. pulmonary arterioles carry carbon dioxide rich blood from the right atrium to the lungs
-the blood enters the capillary beds surrounding the alveoli, where carbon dioxide is exchanged for oxygen
-oxygenated blood exits the lungs through the pulmonary venules to be taken back to the left atrium
-from the left atrium, the blood flows to the left ventricle, which pumps it into body-wide circulation

19. Poor oxygenation in the blood of study participants who have surfactant insufficiency would likely be due to a decrease in what lung volume?

20. Where does air enter from?

21.
-the tube that carries air from the mouth and nasal cavities to the lungs
-rigid tube of cartilaginous rings

22. increased pH of blood can do what to the ventilation rate?

23. left ventricles deliver blood to

24. Describe the gas exchange between the lungs and the heart

25. Chronic obstructive pulmonary disease (COPD) is a disease of the lungs characterized by breakdown of the alveolar spaces. One of the common symptoms is barrel chest, in which the lungs become hyperinflated due to an inability to push out excess air. A decrease in which of the following lung volumes most contributes to the barrel chest symptom?
